Summary: Prism adaptation is a useful method to study sensorimotor adaptation, and the cerebellum plays an important role in the transfer of after-effects. This study aimed to explore whether anodal stimulation of the cerebellum could enhance after-effects transfer from throwing to pointing in novice participants. The results showed that active stimulation did not have significant beneficial effects on error reduction or throwing after-effects, but it had an effect on the longitudinal evolution of pointing errors and on pointing kinematic parameters during transfer assessment.

Summary: Long-term potentiation (LTP) and long-term depression (LTD) are cellular mechanisms related to learning and memory. LTD has a specific role in hippocampus-dependent associative learning and information encoding, reducing excitatory synapses and restricting the effects of LTP. It acts in conjunction with LTP to contribute to learning.

Summary: The study found that Acetamiprid reduces glutamate levels, affects the expression of NMDA receptor subunits in the hippocampus, leading to impaired memory consolidation at low doses, and loss of neural cells in the dentate gyrus area at high doses.

Summary: This study investigated the involvement of the cerebellum in temporal recalibration by using cerebellar transcranial direct current stimulation (ctDCS). The results showed that ctDCS improved temporal recalibration in auditory modality but not in vision. Specifically, anodal ctDCS enhanced sensorimotor recalibration in active conditions, while it facilitated inter-sensory recalibration in passive conditions with larger delays. These findings suggest a role of the cerebellum in supra-modal temporal recalibration and highlight the potential use of anodal ctDCS in facilitating temporal recalibration in sensorimotor and inter-sensory contexts.

Summary: The cerebellum is associated with fine motor control, motor learning, and timing of actions. Despite its well-described anatomy and identified synaptic plasticity, the computation performed by the cerebellar cortex is still debated. Recent advances suggest that the cerebellum stores internal models of body coordinates, specific to the task and locomotor context of each individual.

Summary: Lesions affecting the anterior thalamic nuclei may be responsible for diencephalic amnesia, similar to how hippocampal lesions cause temporal lobe amnesia. The core element of diencephalic amnesia seems to be the loss of information in hippocampal output regions following anterior thalamic pathology, possibly due to the direct connections between the two areas.

Summary: The study used 2-photon calcium imaging to observe the spatial encoding differences between left and right dentate gyrus granule cells in mice. The results showed that the left dentate gyrus exhibited better spatial tuning, context-selectivity, and place field reliability compared to the right dentate gyrus.

Summary: Sensory errors induce two types of behavioral changes in speech articulation: rapid compensation within a movement and longer-term adaptation of subsequent movements. Previous theories suggested that speech sensorimotor adaptation only occurs after repeated exposure to auditory perturbations, but new research shows that learning can also occur after a single exposure to auditory errors.

Summary: Active exploration of novel spatial environments enhances memory for explicit information, potentially through dopamine release in the brain. This study found that exposure to spatial novelty led to slower deadaptation during a sensorimotor adaptation task, suggesting stronger sensorimotor representations induced by novelty-induced dopaminergic effects.

Summary: This study investigates the differential contributions of hippocampal activity to experience-dependent learning of trajectories across spatial and relational contexts. The results indicate that the synchronous reactivation of hippocampal activity plays different roles in the evaluation and initiation of trajectories in navigational and non-navigational contexts.

Summary: Ensemble statistics can provide a gist of a visual scene through mean estimation without detailed analysis of individual items. The equivalent noise paradigm is often used to measure the impact of internal variance, assuming that additional neural activity in high variance does not affect the averaging efficiency.

Summary: The study found that in three-dimensional space, grid cells in rats exhibit different firing patterns compared to two-dimensional space, with more variable and irregularly arranged firing fields. This suggests that the self-organization of grid cells is influenced by the structure and movement affordances of the environment.

Summary: The study explores the relationship between cerebellum-dependent VOR adaptation and structural and functional changes during aging. It finds that long-term plasticity and intrinsic plasticity play important roles in maintaining stable VOR function. The research also highlights the value of computational epidemiology in understanding discrepancies in human cross-sectional studies, as well as the predictive significance of residual fiber quantity in encoding the peak and trough of VOR trajectories.

Summary: Early direction-selective neurons are considered the main neural basis for motion perception, but actual perception may rely more on tracking object position. Experimental results show that perceived motion can be influenced by form information or be independent of it under different conditions.

Summary: This study examined the activation patterns in the hippocampus and the striatum during visual coding. The results showed that the hippocampus was involved in all types of cue-based navigation, while the striatum was more strongly recruited in the presence of geometric cues. Furthermore, unique neural signatures were associated with each spatial cue.

Summary: The hippocampus is crucial for encoding, organizing, and using structured representations to plan for the future. This review focuses on examining the role of 'splitter cells' in understanding hippocampal function and proposes two major theoretical ideas about temporal context and state inference. The findings support both theories but also highlight the need for further research to refine our understanding of hippocampal function.

Summary: The study challenges the hypothesis that allocentric spatial coding develops later and deteriorates earlier than egocentric spatial coding. The use of landmarks for navigation is difficult for children and aged individuals, but introducing geometric cues can improve their allocentric navigation performance. Landmark processing follows an inverted-U dependence on age, while spatial geometry processing is conserved.

Summary: This paper studies the problem of binary agreement in a spiking neural network (SNN) and proposes a network model that achieves agreement with O(n) auxiliary neurons and in O(logn) time. It also introduces a subclass of SNNs called size-independence, which has biologically plausible properties. The paper proves that solving agreement and Winner-Take-All problems in this model requires omega(n) auxiliary neurons, making the agreement network size-optimal.
